everyone.
I'm analyzing a two-channel microarray following an example from Bioconductor Case Studies book. I'm stuck in this error:
invalid class “NChannelSet” object: featureNames differ between assayData and featureData Does anyone know how to fix it?
The line that resulted in the error is:
assayData(NORM_dat) = assayDataNew(A=(r+g)/2, M=r-g)
Some info on my objects:
class(NORM_dat)
[1] "NChannelSet"
attr(,"package")
[1] "Biobase"
[1] "AnnotatedDataFrame"
attr(,"package")
[1] "Biobase"
Thank you so much!
